Agronomic Yields of Perennial Crops — GLBRC Biofuel Cropping System Experiment
Data in the KBS GLBRC core database may not be published without written permission of the lead investigator or project director Full terms of use
Agronomic yields, expressed as dry matter, from machine harvests of the main plot and subplots of BCSE herbaceous perennial crop treatments (G4-G7, G9-G10, depending on year) and from clear-cutting of the woody poplar treatment (G8). Harvesting methods and equipment are recorded in the GLBRC Agronomic Log.
This datatable is part of the Agronomic Yields dataset.
This dataset contains the yields from machine harvests for all treatments (G1-G10) of the GLBRC Biofuel Cropping System Experiment (BCSE). Yields are measured in each treatment replicate (R1-R5) during normal crop harvest by machine harvesters appropriate to each crop, as recorded in the KBS Aglog.
This dataset also includes yields from two different subplot studies on 1) stover removal vs stover non-removal and 2) plus nitrogen vs no nitrogen fertilization. See the BCSE – Sampling protocol for further description of subplot management and location.
